The four stages of cellular respiration do not function independently. instead, they function as

The four stages of cellular respiration are coupled.

Explanation:

Cellular respiration refer to the process by which cells release chemical energy in the form of adenosine triphosphate (ATP), to carry out cellular activities.

The aerobic respiration requires oxygen to produce energy, ATP. It consists of a series of four biochemical steps, which are coupled together.

The four stages are: Glycolysis, Oxidative decarboxylation of Pyruvate or Link reaction, Citric acid cycle or Krebs cycle, and Oxidative phosphorylation or electron transport chain.
